摘要： This disclosure relates to management of a secondary component carrier by a wireless device when using carrier aggregation. According to one embodiment, a primary component carrier for communication between a base station and a wireless device may be configured according to a first wireless communication technology. A secondary component carrier may also be configured. The wireless device may detect a trigger condition to deactivate the secondary component carrier. In response, the wireless device may modify its feedback to the base station with respect to channel conditions for the secondary component carrier to cause the base station to deactivate the secondary component carrier.

摘要： While operating in connected discontinuous reception (C-DRX) mode, a wireless communication device may initiate handover operations when a neighboring base station is determined by the wireless communication device to be a better serving cell than a base station operating as the current serving cell for the wireless communication device. Instead of transmitting a measurement report to the current serving cell, the wireless communication device may select one of the neighboring base stations as the new serving cell, responsive to measurements of the current serving cell and the neighboring cells performed by the wireless communication device during the on-duration of the C-DRX cycle. This enables a longer C-DRX cycle, which leads to the wireless communication device saving more power during non-real-time sensitive background data transmissions, while also avoiding higher handover failure rates and extra Radio Resource Control signaling that may need to be performed as a result of radio link failure.

摘要： Systems, methods, and mechanisms for performing ROHC header compression on TCP packets with MPTCP option enabled. A compressor may determine that a first portion of the stream of data packets is formatted according to the transmission control protocol (TCP) with a multipath TCP (MPTCP) option enabled. The compressor may establish context with a corresponding decompressor and may operate in one of three modes of compression based on the context. In some embodiments, when the context indicates that the corresponding decompressor supports decompression of TCP data packets with MPTCP option enabled, the compressor may operate in a first or second mode of compression. In some embodiments, when the context indicates that the corresponding decompressor does not support decompression of TCP data packets with MPTCP option enabled, the compressor may operation in a third mode of compression.

摘要： In some aspects, the present disclosure relates to a method for performing packet flow description (PFD) management, the method including establishing a Quality-of-Service (QoS) flow between a user equipment (UE) and a core network (CN) for a data flow of an application, creating, by the UE, a UE-requested packet flow description (PFD) upon a change in the data flow, sending, from the UE to the CN, a request to the CN for updating a CN PFD to an updated PFD using the UE-requested PFD, receiving, at the UE from the CN, a downlink (DL) packet mapped to the QoS flow using the updated PFD.

摘要： Apparatuses, systems, and methods for Reflective Quality of Service (RQoS) enhancements. Methods may include enhancements for both UE behavior and network function behavior. Network function behaviors may include enhancements to UPF behavior and SPF behavior. Enhancements to RQoS may include methods for resetting an RQoS indicator (RQI) bit for downlink packets of a flow destined for a UE, methods for generating a flow ID to include in a SDAP header destined for a UE, methods for using the flow ID to limit L3 and L4 header parsing, methods for sending/receiving feedback regarding processing of the RQI bit, methods for maintaining a QFI mapping table, methods for skipping parsing of SDAP header fields, methods for specifying and signaling a QoS Flow Identifier (QFI) range to a UE, methods for limiting downlink header parsing, methods for updating a QFI, and methods for performing high efficiency RQoS processing.

摘要： Embodiments are presented herein of apparatuses, systems, and methods for a user equipment (UE) device to adaptively provide enhanced the quality of service (QoS) for an application. The UE may request a dedicated bearer or flow for communications conducted over a network between a UE application and a server associated with the application. The UE may use various information, including a QoS profile associated with the application, to determine requested QoS parameters and/or determine whether to provide the enhanced QoS functionality, e.g., whether to request the dedicated bearer/flow from the network. These techniques may tend to provide more appropriate QoS to the application, which may improve user experience.

摘要： A user equipment and a method performed by the user equipment. The user equipment includes a transceiver configured to enable the user equipment to establish a connection with a first network and a second network, the first network configured to provide signals to control a transmit power of the transceiver and a processor configured to control the transmit power of the transceiver. The processor controls the transmit power by determining at least one network operation of the user equipment, the network operation associated with a configuration of the connection with the LTE network, receiving a signal from the LTE network indicating an increase in the transmit power to be used and performing a power operation that adjusts the transmit power of the transceiver less than the increase indicated in the signal.

摘要： A user equipment (UE) and corresponding methods to conserve power by the UE. The UE includes a transceiver, the transceiver configured to enable the UE to establish a connection with a Long Term Evolution (LTE) network and configured to operate using a Connected Discontinuous Reception (CDRX) functionality. The processor controls the transceiver by receiving an uplink (UL) grant at a first subframe of a frame of a cycle of the CDRX functionality, transmitting data based upon the UL grant at a predetermined second subframe, and receiving a response from the LTE network corresponding to one of an acknowledgement (ACK) and a negative ACK (NACK) at a predetermined third subframe. The processor deactivates the transmitter for a remainder of the frame based or deactivates a receiver for a remainder of the frame based upon whether the ACK is received.
